Selecting a 14 mm bore bearing

The bore fixes the shaft, not the bearing capacity. At 14 mm the catalog spans 18–22 mm outside diameter: the light sections suit compact housings and moderate duty, while the larger ODs use bigger rolling elements and carry substantially more load. Select first by the required dynamic load rating C for the calculated L10 life, then by available radial space.

For a rotating inner ring a j5 shaft seat with an H7 housing is the usual starting point; an interference fit plus thermal growth consumes internal clearance, so C3 is the common industrial default rather than CN. Sealed variants (-2RS, -ZZ) trade a small amount of speed for contamination protection and maintenance-free operation — compare the sealed and open versions of the same envelope before substituting one for the other.

Frequently asked questions

What bearings have a 14 mm bore?

This index lists 11 verified bearing models with a 14 mm (0.551 in) bore across 1 bearing type, from 18 to 22 mm outside diameter. Open any model for the full specification table, seal/clearance options and graded cross references.

How do I choose between the 18–22 mm OD options for a 14 mm shaft?

On a fixed 14 mm bore, a smaller outside diameter means a lighter section for limited housing space and moderate load; a larger OD with a wider ring carries more radial and axial load and lasts longer at the same duty. Compare the C dynamic load rating in each model table, then match seal type, internal clearance (CN/C3/C4) and precision class to the actual mounting and operating temperature.

What shaft fit and bore code apply to 14 mm bearings?

A 14 mm bore on a rotating inner ring normally uses a j5 shaft seat with an H7 housing bore (verify against the catalogue for heavy or stationary-ring duty). Bore diameters below 20 mm follow the 10/12/15/17 mm exception table rather than code × 5.
